RF interface: ISO/IEC 14443 Type A

  • Contactless interface compliant with ISO/IEC 14443-2/3 A
  • Low Hmin enabling operating distance up to 100 mm (depending on power provided by the PCD and antenna geometry)
  • Fast data transfer: 106 kbit/s, 212 kbit/s, 424 kbit/s, 848 kbit/s
  • 7 bytes unique identifier (option for Random ID)
  • Uses ISO/IEC 14443-4 transmission protocol
  • Configurable FSCI to support up to 128 bytes frame size (new)

Nonvolatile memory

  • 2 kB, 4 kB, 8 kB, 16 kB, or 32 kB NV
  • Data retention of 25 years
  • Write endurance typical 500 000 cycles
  • Fast programming cycles (erase/write)

NV-memory organization

  • Flexible file system: user can freely define application structures on PICC
  • Virtually no limitation on the number of applications per PICC (new)
  • Up to 32 files in each application (6 file types available: Standard Data file, Back up Data file, Value file, Linear Record file, Cyclic Record file, and Transaction MAC file)
  • File size is determined during creation (not for Transaction MAC file)


  • Common Criteria Certification: EAL5+ (Hardware and Software)
  • Unique 7 bytes serial number for each device
  • Optional “RANDOM” ID to enhance security and privacy
  • Mutual three-pass authentication
  • Mutual authentication according to ISO/IEC 7816-4
  • Flexible key management: 1 card leader key and up to 14 keys per application
  • Hardware DES using 56/112/168 bit keys featuring key version
  • Hardware AES using 128-bit keys featuring key version
  • Data authenticity by 8 bytes CMAC
  • Data encryption on RF-channel
  • Authentication on application level
  • Hardware exception sensors
  • Self-securing file system
  • Backward compatibility to MF3ICD40: 4 byte MAC, CRC 16

New features on MIFARE DESFire EV2

  • MIsmartApp (Delegated Application Management)
  • Memory reuse in DAM applications (Format Application)
  • Transaction MAC on application level
  • Multiple Keys Sets per application with fast key rolling mechanism (up to 16 sets)
  • Accessing files from any two applications during a single transaction
  • Multiple keys assignments for each file access right (up to 8)
  • Virtual Card Architecture for enhanced card/application selection on multi-VC devices with privacy protection
  • Proximity Check for protection against Relay Attacks
  • Originality Check for proof of genuine NXP’s product
  • New EV2 Secure Messaging based on AES (similar to MIFARE Plus’s secure messaging)

ISO/IEC 7816 compatibility

  • Supports ISO/IEC 7816-4 file structure (selection by File ID or DF name)

  • Supports ISO/IEC 7816-4 INS code ‘B0’ for READ BINARY
  • Supports ISO/IEC 7816-4 INS code ‘D6’ for UPDATE BINARY
  • Supports ISO/IEC 7816-4 INS code ‘B2’ for READ RECORDS
  • Supports ISO/IEC 7816-4 INS code ‘E2’ for APPEND RECORD
  • Supports ISO/IEC 7816-4 INS code ‘84’ for GET CHALLENGE
  • Supports ISO/IEC 7816-4 INS code ‘88’ for INTERNAL AUTHENTICATE
  • Supports ISO/IEC 7816-4 INS code ‘82’ for EXTERNAL AUTHENTICATE

Special features

  • Transaction-oriented automatic anti-tear mechanism
  • Configurable ATS information for card personalization
  • Backward compatibility mode to MIFARE DESFire EV1 and D40 (MF3ICD40)
  • Optional high input capacitance (70pF) for small form factor designs (MF3DHx2)
